This looks you might have a bad install. I would remove
site-packages/matplotlib and try re-installing cleanly. If the error
persists, make sure that you don't have a copy of backend_ps.py
anywhere in your PYTHONPATH (do 'locate backend_ps' to find out if
there are any errant copies lying around.).
Your example runs fine on my system.
